Hardnell-250:

Hardnell-250 is s a hardfacing electrode operating on AC/DC() impact loads depositing an air hardening weld metal. The deposit displays HARDNELL-250 is and has excellent resistance to rolling and sliding friction. The weld deposit is machinable. Weld metal hardness - On mild steel two layers : 250-280 BHN

Identification:Name Printed

Applications:: Ideal for rail points and crossings axles, wheels, gear shafts, couplings, pinnion teeth, rollers sprockets, etc.

Notes on usage:

Use short arc.
Use low currents.
Ensure the electrodes are dry. In case of moisture pick-up, redry the electrodes at 125°C for one hour.
If the base material has the carbon content of more than 0.25%, a buffer layer using a low hydrogen electrode is recommended.
